Critical reading of science-based news reports: Establishing a knowledge skills and attitudes framework

A recognised aim of science education is to promote critical engagement with science in the media. Evidence would suggest that this is challenging for both teachers and pupils and that at science education does not yet adequately prepare young people for this task. Furthermore, in the absence of clear guidance as to what this means and how this may be achieved it is difficult for teachers to develop approaches and resources that address the matter and that systematically promote such critical engagement within their teaching programmes. Twenty-six individuals with recognised expertise or interest in science in the media, drawn from a range of disciplines and areas of practice, constituted a specialist panel in this study. The question this research sought to answer was ‘what are the elements of knowledge, skill and attitude which underpin critical reading of science based news reports’? During in-depth individual interviews the panel were asked to explore what they considered to be essential elements of knowledge, skills and attitude which people need to enable them to respond critically to news reports with a science component. Analysis of the data revealed fourteen fundamental elements which together contribute to an individual’s capacity to engage critically with science-based news. These are classified in five categories ‘knowledge of science’, ‘knowledge of writing and language’, ‘knowledge about news, newspapers and journalism’, ‘skills’ and ‘attitudes’. Illustrative profiles of each category along with indicators of critical engagement are presented. The implications for curriculum planning and pedagogy are considered.

Green synthesis of biodiesel using ionic liquids

This paper is a hybrid starting with an overview and history of biodiesel synthesis and finishing with a description with some of our latest unpublished data. Initially, we examine "green" ways of obtaining biodiesel using ionic liquids, which can have an acidic or basic functionality, and can function both as a solvent and catalyst for the (trans)esterification reaction to obtain biodiesel. Both animal and vegetable resources can be utilized as a resource for (trans)esterification reactions depending on the geographical area. Biodiesel is of great interest because it enables motor vehicle transport using a renewable resource, while reducing the amount of carbon dioxide from fossil fuels being released into the environment.

Categorising Korean Cult: The Reputation and Reception of Save the Green Planet!

This article examines the international release of the South Korean film Save the Green Planet! and argues that this is an example of a film whose cult reputation was pre-sold to audiences on the basis of constructed associations between Korean cinema and excessive violence. This article also considers the divided critical reception of Save the Green Planet! as experts from different fields argued over the value and meaning of the film.

Systematics of the marine microfilamentous green algae Uronema curvatum and Urospora microscopica (Chlorophyta)

The microfilamentous green alga Uronema curvatum is widely distributed along the western and eastern coasts of the north Atlantic Ocean where it typically grows on crustose red algae and on haptera of kelps in subtidal habitats. The placement of this marine species in a genus of freshwater Chlorophyceae had been questioned. Molecular phylogenetic analysis of nuclear-encoded small and large subunit rDNA sequences reveal that U. curvatum is closely related to the ulvophycean order Cladophorales, with which it shares a number of morphological features, including a siphonocladous level of organization and zoidangial development. The divergent phylogenetic position of U. curvatum, sister to the rest of the Cladophorales, along with a combination of distinctive morphological features, such as the absence of pyrenoids, the diminutive size of the unbranched filaments and the discoid holdfast, warrants the recognition of a separate genus, Okellya, within a new family of Cladophorales, Okellyaceae. The epiphytic Urospora microscopica from Norway, which has been allied with U. curvatum, is revealed as a member of the cladophoralean genus Chaetomorpha and is herein transferred to that genus as C. norvegica nom. nov.

Water temperature and internesting intervals for loggerhead (Caretta caretta) and green (Chelonia mydas) sea turtles

Temperature loggers were attached to the carapace of green turtles (Chelonia mydas) at Ascension Island and Cyprus and to loggerhead turtles (Caretta caretta) at Cyprus, in order to record the ambient temperature experienced by individuals during the internesting interval, i.e. the period between consecutive clutches being laid. Internesting intervals were relatively short (10-14 days) and mean ambient temperatures relatively warm (27-28degreesC), compared to previous observations for these species nesting in Japan, although a single internesting interval versus temperature relationship described all the data for these two species from the different areas. The implication is that water temperature has both a common and a profound effect on the length of the internesting interval for these two species: internesting intervals are shorter when the water is warmer.

Basic auditory processing skills and phonological awareness in low-IQ readers and typically developing controls

We explore the relationships between basic auditory processing, phonological awareness, vocabulary, and word reading in a sample of 95 children, 55 typically developing children, and 40 children with low IQ. All children received nonspeech auditory processing tasks, phonological processing and literacy measures, and a receptive vocabulary task. Compared to age-matched controls, the children with low IQ and low reading skills were significantly impaired in auditory and phonological processing, whereas the children with low IQ and preserved reading skills were not. There were also significant predictive relations between auditory processing and single word reading. Poor auditory processing was not dependent on low IQ, as auditory processing was age appropriate in the low-IQ children who were good readers.
